A combination therapy pad that includes a first layer and a second layer operatively coupled to the first layer. A fiber-optic array is disposed between the first layer and the second layer. A third layer is operatively coupled to the first layer. The third layer includes a vacuum tube in fluid communication with a vacuum source and a therapeutic fluid tube in fluid communication with a therapeutic fluid source. The third layer provides at least one of vacuum therapy and therapeutic fluid treatment to a wound area.

A treatment system for debriding a treatment area of a tissue site and applying negative pressure is disclosed. In some embodiments, the treatment system may include an ultrasonic bubble generator fluidly coupled to a negative-pressure source, fluid source, and a dressing. Fluid may be drawn from the fluid source to the ultrasonic bubble generator, whereby micro-bubbles and ultrasonic waves may be generated in the fluid before the fluid is instilled to the dressing.

A bandage device having a flexible body with a plurality of fluid reservoirs thereon each containing a liquid topical treatment therein. Mixing areas located between the respective fluid reservoirs on the bandage provide for mixing and formation of liquid mixtures of the respective liquid topical treatments flowing thereto from the respective fluid reservoirs located adjacent thereto. The liquid mixtures from the mixing areas when absorbed through the skin of a wearer of the bandage yield an enhanced synergistic effect exceeding that of the individual fluids such medications or essential oils.

A wound care device for delivering topical oxygen therapy, negative pressure wound therapy, and a low intensity vacuum therapy for treatment of a wound. The wound care device may include an oxygen supply MEA, an oxygen consuming MEA, a vacuum pump and motor, a pressure sensor, and a power supply and electronic controls. A dressing may be connected to the wound care device for administering topical continuous oxygen therapy and simultaneous negative pressure wound therapy to a wound. A canister or exudate trap may be positioned between the dressing and the vacuum supply port of the vacuum pump to collect and store exudates from the wound. The canister may be combined with the dressing.

An oxygen-generating wound dressing is provided. The oxygen-generating wound dressing comprises a housing and a wound contacting layer. The interior of the housing comprises a barrier member to divide the housing into a reactant receptacle and a wound contacting layer receptacle. The reactant receptacle of the housing further comprises a first reactant receptacle, a second reactant receptacle, a check valve disposed between the first reactant receptacle and the second reactant receptacle, a flow regulating device disposed on the second reactant receptacle and a gas deliver tube for fluidly communicating the first reactant receptacle and the wound contacting layer receptacle. The entrance speed of the second reactant into the first reactant receptacle can be controlled by the flow regulating device. The oxygen partial pressure can be maintained preferably and the wound healing can be improved by using the oxygen-generating wound dressing of the present invention.

A wound-care system includes a first pump fluidly coupled to an oxygen source. An oxygen concentrator is fluidly coupled to the first pump. A humidification system is fluidly coupled to the oxygen concentrator. A wound dressing is fluidly coupled to the humidification system and to an exudate chamber. A negative-pressure tube fluidly is coupled to the exudate chamber. A first valve is disposed between the first pump and the oxygen concentrator. A second valve is disposed between the oxygen concentrator and the wound dressing. A third valve is disposed in the negative-pressure tube. Selective activation of the first pump, the first valve, the second valve, and the third valve facilitates delivery of at least one of individual, sequential, or simultaneous negative-pressure treatment and oxygen-rich fluid treatment to the wound via the wound dressing.

Apparatus and methods to treat skin defects include a pump with reservoirs for a pressurization gas and a fluid. Upon activation, the pump generates a gas introduced into the gas reservoir, a movable wall of which displaces a movable wall of a fluid source, thus dispensing the fluid into the dressing to spread throughout irrespective of orientation of the dressing, maintaining a transport fluid (e.g. carrier) in the dressing and in contact with a skin defect being treated. The dressing may have a distribution network, and multiple members, dispensing the fluid into the dressing and in contact with a skin defect being treated.

This disclosure includes wound dressings and systems with remote oxygen generation for topical wound therapy and related methods. Some systems include a dressing for facilitating delivery of oxygen to the target tissue, the dressing having: a first manifold that defines a plurality of gas passageways and is configured to allow communication of oxygen to the target tissue; a gas-occlusive layer configured to be disposed over the first manifold and coupled to tissue surrounding the target tissue such that: an interior volume is defined between the gas-occlusive layer and the target tissue; and the gas-occlusive layer limits escape of oxygen from the interior volume between the gas-occlusive layer and the tissue surrounding the target tissue; a container outside the interior volume, the container having a sidewall that defines a chamber configured to be in fluid communication with the interior volume; and an oxygen-generating material disposed within the chamber of container and configured to release oxygen when exposed to water.

A wound-care system includes a first pump fluidly coupled to an oxygen source. An oxygen concentrator is fluidly coupled to the first pump. A humidification system is fluidly coupled to the oxygen concentrator. A wound dressing is fluidly coupled to the humidification system and to an exudate chamber. A negative-pressure tube fluidly is coupled to the exudate chamber. A first valve is disposed between the first pump and the oxygen concentrator. A second valve is disposed between the oxygen concentrator and the wound dressing. A third valve is disposed in the negative-pressure tube. Selective activation of the first pump, the first valve, the second valve, and the third valve facilitates delivery of at least one of individual, sequential, or simultaneous negative-pressure treatment and oxygen-rich fluid treatment to the wound via the wound dressing.

A wound dressing system having a capillary membrane system arranged in a pouch-shaped wound dressing that is closed at its outer edge. The pouch-shaped wound dressing having an upper face, a lower face, and an interior formed from planar materials with the lower face permeable to fluids. The capillary membrane system is arranged into the interior of the pouch-shaped wound dressing.
